>E. coli have only 1 membrane, so if you're expressing a membrane-bound
version of your protein it should come as no surprise that the expression
is poor. I think you have 3 options:
1. Accept the low expression level and work with it,
2. increase the expression level through experimenting with different
promoter constructs and deal with the inclusion body mess
that results,
3. generate a truncated, soluble version of your protein or fuse it to
something that renders it soluble.
